The Data Strobe is HRD or HWR in the Dual Data Strobe mode and HDS in the Single Data Strobe mode.
HTA, HDRQ, and HRST may be programmed as active-high or active-low. In the example timing diagrams, HDRQ and HRST
are shown as active-high and HTA is shown as active low.
The Read Data Strobe is HRD in the Dual Data Strobe mode and HDS in the Single Data Strobe mode.
The Write Data Strobe is HWR in the Dual Data Strobe mode and HDS in the Single Data Strobe mode.
HTA requires an external pull-down resistor if programmed as active high (HTAP = 0); or an external pull-up resistor if
programmed as active low (HTAP = 1). The resistor value should be consistent with the DC specifications.
HIRQ requires an external pull-up resistor if programmed as open drain (HIRD = 0). The resistor value should be consistent
with the DC specifications.
“LT” is the value of the latency timer register (CLAT) as programmed by the user during self configuration.
LT ≥ 1.
